Abstract (en)

[origin: WO2010083863A1] The invention relates to a control device for an automated geared transmission, in particular a dual clutch transmission. In such transmissions, two gears of a partial transmission must not be simultaneously engaged because the transmission would be blocked such that the motor vehicle could no longer be kept under control while driving, and the transmission would be damaged. The aim of the invention is to design a control device for an automated geared transmission in which two gears of a partial transmission are prevented in a simple manner from being simultaneously engaged. Said aim is achieved by providing the gear actuation system (62) with a first and a second gear slide (SS GS73, SS GS51) which allow a shifting mechanism (18, 19) to be selected. A second gear control pressure of the second gear slide (SS GS51) counteracts the first gear control pressure on the first gear slide (SS GS73) such that the first gear slide (SS GS73) can be blocked using the second control pressure.
